Abstract

Polymer self-assembly plays a crucial role across various fields, such as biomedicine, catalysis, and optoelectronics. Over the years, self-assembly in solution has attracted significant interest. In 2007, our group, in collaboration with Prof. Ian Manners, published a groundbreaking article in Science on living crystallization-driven self-assembly (CDSA) of amphiphilic block copolymers featuring a crystalline core-forming block. This study focused on polyferrocenylsilane block copolymers (PFS BCPs). Living CDSA operates similarly to living polymerization, enabling the precise fabrication of micelles with predictable shapes and dimensions. The crystalline nature of the core-forming block promotes the formation of structures with low interfacial curvature, such as cylinders and platelets, which are rarely formed in traditional self-assembly techniques based on microphase separation.

结晶驱动自组装形成的三维聚合物胶束

聚合物自组装在生物医学、催化、光电等领域发挥着至关重要的作用。多年来，溶液中的自组装引起了人们极大的兴趣。2007年，我们的团队与Ian Manners教授合作，在《科学》杂志上发表了一篇开创性的文章，内容是两亲性嵌段共聚物的活结晶驱动自组装（CDSA），具有结晶核形成的嵌段。本文主要研究了聚二茂铁基硅烷嵌段共聚物（PFS bcp）。活性CDSA的操作类似于活性聚合，可以精确地制造具有可预测形状和尺寸的胶束。成核块的结晶性质促进了低界面曲率结构的形成，如圆柱体和片状结构，这些结构在传统的基于微相分离的自组装技术中很少形成。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
